How to use improved Eloquent accessors and mutators in Laravel 9.x

Hello friends! As you may know now, since the version 9 of Laravel you can use the new way to define Eloquent accessors and mutators

// Before

public function getNameAttribute($value)
{
  return strtoupper($value);
}

public function setNameAttribute($value)
{
  $this->attributes['name'] = $value;
}


// After, in Laravel 9.x, with improved Eloquent accessors & mutators

use Illuminate\Database\Eloquent\Casts\Attribute;

public function (): Attribute
{
  return new Attribute(
    get: fn ($value) => strtoupper($value),
    set: fn ($value) => $value,
  );
}
